可能要搞清楚這個用途

All Koding VMs are optimized for software development, and they're automatically turned off one hour after you leave the site.
翻譯:離開一個小時後會自動關閉

If you want your VM to stay online, you can mark it as "Always on", and we will never turn it off.
翻譯:如果你要一直保持VM啟動，要設定 "Always on"，但如果你用免費帳戶這功能是沒有的，1xCPU 1xGB RAM 3GB Disk 1xTotal VMs 0xAlways on VMs

This is great for lightweight sites, your personal blog perhaps, or your client presentations. We are not attempting to be a production host, so if you are looking for 24x7x365 availability we might suggest you host your application/site with a specialist hosting company.
翻譯:如果你要 365 天不間斷運行，建議去找其他主機商

簡單的說這個只是可以拿來執行測試用途而已，尤其是免費帳戶，有付錢勉強可以執行一個輕量網站
